Substitute Part Grouping Explanation

The Dialight 5502307F qualifies as a manufacturer-recommended substitute for the 5505307F based on the following substitution criteria:

Matching Parameters:

• Manufacturer: Dialight (same manufacturer ensures design compatibility)
• Series: 550 (same product family)
• Color: Yellow (identical optical output)
• Wavelength - Peak: 585nm (identical spectral characteristics)
• Configuration: Single (same electrical configuration)
• Lens Type: Diffused (identical optical properties)
• Lens Style: Round with Domed Top (identical mechanical form factor)
• Lens Size: 5mm, T-1 3/4 (identical package dimensions)
• Mounting Type: Through Hole, Right Angle (identical PCB interface)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)
• REACH Status: REACH Unaffected (equivalent regulatory compliance)

Allowable Parameter Variations:

• Voltage Rating: 2.2V (original) to 2.1V (substitute) — within acceptable tolerance for LED forward voltage
• Current Rating: 20mA (original) to 10mA (substitute) — lower current operation reduces power consumption
• Millicandela Rating: 34mcd (original) to 6.3mcd (substitute) — reduced brightness output

The 5502307F operates at lower current and voltage with reduced brightness output, making it suitable for applications where power efficiency is prioritized or where full brightness of the original part is not required.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5502307F is the manufacturer-recommended substitute for the obsolete 5505307F. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications subject to environmental directives.

The 5502307F is currently in active production status, providing supply chain continuity and long-term availability compared to the obsolete 5505307F. The substitute operates at reduced current (10mA versus 20mA) and lower brightness output (6.3mcd versus 34mcd), making it suitable for applications where indicator visibility requirements do not demand maximum brightness or where power consumption reduction is beneficial.

Component selection should be based on specific application brightness requirements and circuit design parameters. The identical mechanical form factor and mounting interface ensure direct PCB compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the 5502307F directly replace the 5505307F in existing designs?

A: Yes, the 5502307F provides direct mechanical and electrical compatibility for through-hole right-angle mounting applications. Both components share identical lens size (5mm, T-1 3/4), lens style (round with domed top), and mounting configuration. Circuit design must accommodate the reduced current requirement (10mA versus 20mA) and lower brightness output (6.3mcd versus 34mcd).

Q: What are the key differences between these two parts?

A: The primary differences are current rating (20mA original versus 10mA substitute), voltage rating (2.2V original versus 2.1V substitute), and brightness output (34mcd original versus 6.3mcd substitute). The 5502307F operates at lower power consumption while maintaining identical color (yellow, 585nm peak wavelength) and optical properties (diffused lens, 50° viewing angle).

Q: Is the 5502307F suitable for all applications using the 5505307F?

A: Suitability depends on application brightness requirements. The 5502307F delivers approximately 18.5% of the original brightness output. Applications requiring full brightness of the 5505307F may require circuit modifications or alternative component selection. Applications where indicator visibility is not brightness-critical can use the 5502307F without modification.

Q: What is the packaging difference between these parts?

A: The 5505307F is supplied in standard packaging, while the 5502307F is supplied in bulk packaging. Both maintain identical component specifications and performance characteristics.

Q: Are both parts compliant with environmental regulations?

A: Yes, both the 5505307F and 5502307F are ROHS3 compliant and REACH unaffected, meeting current environmental directive requirements for electronic components.
